This app is targeted to help individuals rate various symptoms of mood disorders to determine the impact it may have on their functioning. This app may help those with major depression, bipolar, anxiety disorders and PTSD quickly determine if they need to speak to their primary care physician about a possible mental health condition that needs treatment.
